ROPE rasrnnnn.

Application fllcgl March 11,1924. Serial No. 6983439.

and its primary object is to provide in connection ,with a rope, a simple, practical and highly efiicient means forfastening an end thereof upon itself for the main purpose of securing the rope to an object to which it 1s ap lied.

further object of the invention is to providea fastener which will cause the rope to tighten upon an object encircled thereby,

by pulling it lengthwise away from the ob 90 ject and still another object is to provide a fastener which will increase its hold upon the rope in ratio to the stress to which it is subjected when the rope is in use.

My invention is particularly appllcable to 33 lines of the kind commonly used for towing motor vehicles and it is adapted for use in connection with ropes made of w1re as well as on ropes composed of hemp or other fibers.

In its use in connection'with a tow line, the invention is particularly advantageous I in that it permits of applying the line without the necessity of crawling. under the vehicle for the purpose of securing an end of 36 the rope to the axle or of passing it around the same. v

An embodiment of my invention has been illustrated in the accompanying drawings in which like characters of reference designate 40 corresponding parts throughout the views and in which- Figure 1 represents the fastener applied to a rope, in the position it occupies in fastening an end of the rope upon itself;

Figure 2 showsa rope provided with fasteners for formin it into an endless loop by securing the on s of the rope together;

Figure 3 represents a detailed elevation of the fastener; and W Figure 4: represents an enlarged section taken on the line 4-4, Figures 1 and 2.

Referring more specifically to the drawings, my improved fastener comprises a spiral 5 preferably made of heavy wire, which at one of its ends is rovided with an eye 6 for the attachment of the r0 7.

It is a distinctive and essential gature of the invention that the inside diameter of the spiral exceeds that of the rope to which the fastener is applied and that the eye at the end of the fastener is positioned to one side of the passage presented by the interior of the spiral so as not to interfere with the free lengthwise movement of a rope through said passage.

The end of the rope is tied to the eye of the fastener by intertwining its strands so that the diameter of the rope is not materially changed to prevent of its moving freely through the interior passage of the spiral to the very point at which the fastener is attached.

In Figure 1 of the drawings, the rope is shown as fastened upon itself by passin it through the spiral of a fastener attache at an end thereof. The loop thus-formed has been shown as applied to an axle 8, and it will be evident that by ullin the body portion of the rope away From t e axle, the loop will be tightened upon the same.

In Figure 2, the rope is formed into an endless loop by passing it through the spirals of fasteners applied at opposite ends thereof and by pulling the end-portions of the rope in opposite directions, the fasteners are brought together until their further movement is arrested by engagement of the strands of the rope drawn through the eyes of the fasteners.

I am aware that devices somewhat similar to the present invention have been employed hereto ore for fastening a rope or other flexible connection by CIIIIIPlII or otherwise twisting it within a spiral so that it remains immovably in place therein, and I desire it understood thatmy invention resides solely in the arrangement of the eye to the spiral and in the combination of a spiral with a -"rope of less diameter than the interior passage thereof, as specified in the hereunto appended claims.

What I claim and desire to secure by Letters Patent is:

1. A rope fastener comprising a spiral roviding a straight passage for a rope of esser diameter, and an eye at an end of the spiral ositioned at a side of the passage.

2. T e combination with a spiral provid- 6 ing a straightinterior pamage and terminatmg in an eye at a side of said passage, of a rope of lea diameter than the tened to said eye.

passage, fas- 3. The combination with a spiral providmg a straight interior passage and terminating in-an eye at a side of said passage, of a rope of less diameter than the passage, fastened to said eye by intertwisted strands.

In testimony whereof I havev aflixed my signature.

HENRY M. SIEMANN'.
